The software codes can be implemented witha software application written in any suitable programming language andmay be stored in a memory (for example, the memory 140), and executed bya controller or processor (for example, the controller 130).

The image display apparatus 100 can be, e.g., a DTV, an MP3 player, acomputer, a mobile terminal, a handset, a user equipment, a PDA, etc.

As shown in FIG. 1, the first tuner 111 receives an image through achannel selected by, e.g., a user using a remote controller or otherinput unit. The selected channel here indicates a main channel forviewing which is selected by a user through the image display apparatus.For example, in response to the user's selection of a particularchannel, the first tuner 111 may tune to that particular channel. Andbroadcasting signals of the channel selected and tuned to by the firsttuner 111 are processed by the controller 130, and are output throughthe output unit 120.

For instance, the first tuner 111 may receive an image from a channelcorresponding to a region/portion of a screen of the display unit 123having a cursor located on that region.

As shown in FIG. 1, while an image received by the first tuner 111 isdisplayed by the output unit 120, the second tuner 112 sequentiallyreceives images through one or more channels. Here, the one or morechannels that are tuned to by the second tuner 112 may or may notinclude the channel being currently tuned to by the first tuner 111.

The second tuner 112 is differently operated according to the number ofchannels through which images are being currently received.

When receiving an image through one channel, the second tuner 112continuously receives an image through that one channel. When receivingimages through a plurality of channels, the second tuner 112sequentially receives images through those plurality of channels. Thiscauses images received by the second tuner 112 to be changed accordingto lapses of time. The images and other data received by the first andsecond tuners 111 and 112 are managed by the controller 130. Preferably,images and data from the second tuner are stored in the memory 140 forsubsequent use and reproduction, whereas images and data from the firsttuner are reproduced directly through the output unit 120. However,other variations are possible and part of the present invention.

As shown in FIG. 1, a channel information function may be selected by auser, e.g., using the user input unit 160. The channel informationfunction may allow displaying images from multiple channelssimultaneously on one or more regions of the screen of the display unit123. For instance, once the channel information function is executed,the controller 130 controls the display unit 123 to display the storedimages on one or more regions of the screen of the display unit 123. Thescreen of the display unit 123 may be divided into different regions forrespectively displaying images from multiple channels simultaneously.Here, these regions of the screen may be in a form of certain shape orconfiguration, e.g., a 3-dimensional cube or ball, etc.

The controller 130 may control the screen for displaying the storedimages at one or more regions of the screen to be arranged in a two orthree-dimensional manner, or may control the regions of the screen fordisplaying images received through predetermined similar channels so asto be arranged with an adjacent status with one another. And, thecontroller 130 may display a cursor on one or more of the regions of thescreen for displaying the stored images. As a variations, instead ofhaving different regions of a single screen displaying the imagesrespectively, it may be possible for the apparatus 100 have multipleseparate screens that function like the different regions of a singlescreen.

The controller 130 may also control the display unit 123 to displaychannel guide information about the channels through which the storedimages have been received by the broadcasting reception module 110.

The channel guide information may include any information pertaining toprogram/data of a corresponding channel, and may include, e.g., programrelated information such as running time, synopsis, ratings, and maincharacter information of a program to be broadcast on a correspondingchannel, etc.

The controller 130 may control the display unit 123 to display an imagereceived by the first tuner 111 on the screen having the cursor locatedthereon. The controller 130 may increase a ratio of time taken toreceive an image through a corresponding channel, with respect to timetaken to receive images through all channels.

The controller 130 may perform a video recording function or areservation-video recording function with respect to images receivedthrough one or more channels among the images displayed on the displayunit 123. The video recording function may be a function to store imagesreceived through the broadcasting reception module 110 and broadcastthrough one or more channels, into a storage medium. The storage mediummay include the memory 140, Blue-ray disc, Digital Video Disc (DVD),High Definition DVD (HD DVD), magnetic memory, magnetic disc, opticaldisc, etc.

The reservation video recording function may be a function to storeimages received through the broadcasting reception module 110 for apreset time and broadcast through one or more channels, into a storagemedium. Here, the preset time may be set by a user. The user maydirectly set starting time and ending time for the reservation videorecording function. Alternatively, once a broadcasting program to bereservation video-recorded is selected, the user may set starting timeand ending time of the selected broadcasting program as starting timeand ending time for the reservation video recording function. The imagedisplay apparatus 100 may perform other recording/reproductionfunctions.

The controller 113 may control the display unit 113 to display channelguide information about a channel corresponding to a screen (whenmultiple screens are used) or to a region of a screen (when multipleregions of a single screen are used) having a cursor located thereon.

The controller 113 may perform a video recording function or areservation-video recording function with respect to an image receivedthrough a channel corresponding to the region/screen having a cursorlocated thereon.

As shown in FIG. 1, the memory 140 may store images received by thesecond tuner 112. The images stored in the memory 140 may be deleted asa certain time lapses. Here, the images stored in the memory 140 may bedeleted in a firstly stored order inside the memory 140. For instance,the images and data stored in the memory 140 may be deleted in the orderof storage in the memory 140.

The memory 140 may store images or data recorded when performing a videorecording function or a reservation video recording function.

FIG. 2 is a flowchart for explaining a channel information displaymethod of an image display apparatus according to a first embodiment ofthe present invention. This method implemented in the apparatus 100 ofFIG. 1 is discussed below; however, the method may be implemented inother suitable device. In the present and other embodiments, an ‘image’may include video and/or audio data including one or more of movingimages, programs, data, etc.

Referring to FIG. 2, the first tuner 111 receives an image through afirst selected channel, and the display unit 123 displays the image ofthe first selected channel on a screen of the display unit 123 (S10).During the image display (e.g., while the image from the first selectedchannel is continuously displayed on the entire screen of the displayunit 123), the image display apparatus 100 may sequentially receiveimages through one or more channels to store them (S20). For instance,the second tuner 112 sequentially receives images from one or morechannels for storage in the memory 140.

Once a user selects a channel information function using the user inputunit 160, the controller 130 executes the channel information function(S30). To execute the channel information function, the controller 130controls the display unit 123 to display the stored images on one ormore regions of the screen of the display unit 123 (S40).

When the stored images (e.g., images tuned by the second tuner) aredisplayed on the entire screen, the image received through the firstselected channel may not be displayed on the screen. On the other hand,while the stored images are displayed on certain regions of the screen,the image received through the first selected channel may be displayedon another region of the screen together with the stored images. Thatis, images from different channels may be simultaneously andcontinuously displayed on different regions of the screen, where theseimages are moving images. For instance, programs (e.g., TV programs,movies, shows, etc.) that are broadcast by broadcasters and otherentities on different channels may be received, stored and reproduced onthe screen as they are.

The stored images may be displayed as being arranged in a two- orthree-dimensional manner. For instance, the regions of the screen (orthe screens) for displaying the stored images may be formed in polygonalshapes. In an example, similar channels or channels providing similarimages or programs may be displayed adjacent to each other. Forinstance, the regions of the screen (or the screens) for displayingimages received through predetermined similar channels may be arrangedto be adjacent to one another. The predetermined similar channels mayindicate a set of channels classified as similar channels by abroadcasting provider or a user. The user may group certain channelsinto different groups (e.g., movie channel group, news channel group,etc.) and such groups of channels may be displayed at differentlocations of the screen. For example, if the regions of the screen forsimultaneously displaying the multiple channels of moving images arerepresented in a cube-shape, one side of the cube on the screen maydisplay the movie channel group (movie channels), where another side ofthe cube on the screen may display the news channel group (newschannels), etc.

A cursor may be displayed on one or more regions of the screen (or thescreens) (S50). For instance, the user may be able to move the cursorlocation from one region to another region of the screen where theimages are displayed. By placing the cursor on a region or activatingthe cursor on the region of the screen (e.g., by pressing a button), thechannel displayed on the cursor-identified region may be selected andactivated, whereby that channel may be displayed on the entire screen(e.g., without any other channels being displayed) or on a larger regionof the screen.

Once the channel corresponding to the screen/region having the cursorlocated thereon is activated, the first tuner 111 or the second tuner112 may tune to the activated channel, and display the received imagefrom the activated channel on the screen.

The region of the screen having the cursor located thereon may have itssize gradually increased with respect to the entire screen size as timelapses. For instance, an image displayed on such region may be graduallyenlarged as time lapses since that region is selected (e.g., by thecursor). When a preset time lapses under a state the cursor is displayedor located on one region of the screen, the channel corresponding to theregion having the cursor located thereon may be set as a main channel.Here, the main channel indicates a channel received by the first tuner111, and displayed on the screen by the display unit 123 when a channelinformation function is not executed. For instance, when the cursor isused on the screen to select a particular channel, the first tuner 111may switch from a currently tuned channel to the channel correspondingto the cursor-selected region of the screen. And the images from thatchannel as received by the first tuner 111 may be displayed on theentire screen or a main region of the screen for displaying imagesreceived by the first tuner 111.

While the second tuner 112 receives images through a plurality ofdifferent channels sequentially, the controller 130 may increase a ratioof time taken to receive an image through a channel corresponding to thescreen having the cursor located thereon, with respect to time taken toreceive images through all other channels. For instance, if a cursor islocated over a region D of the screen, then as the second tuner 112sequentially tunes to each of the different channel for a preset timeperiod, the second tuner 112 may tune to a channel corresponding to theregion D much longer than all other channels.

FIG. 3 is an example of a conceptual view for explaining a method forsequentially receiving images through a plurality of channels by asecond tuner and storing the images while displaying a selected channelaccording to an embodiment of the invention.

Sequentially receiving images by the second tuner 112 through aplurality of channels may include receiving images within a preset timethrough one channel among a plurality of channels, and then after thepreset time lapses, receiving images within a preset time throughanother channel among the plurality of channel, and then so on to thenext channel. Here, the preset times for all channels may be the same orvary.

In the example of FIG. 3, the first tuner 111 consecutively receives animage through a selected channel (A). The selected channel (A) maysignify a main channel. The channel (A) selected by the first tuner 111may be displayed on a screen of the display unit 123. Meanwhile, thesecond tuner 112 may sequentially receive images from each of multiplechannels (B1-B9).

More specifically, while an image received through the channel (A)selected by the first tuner 111 is displayed on the screen, the secondtuner 112 sequentially receives images through a plurality of channels(B1-B9). FIG. 3 shows 9 channels; however, the number of channels may bevaried according to a set status and the present invention covers anynumber of channels for the second tuner 112. In one example, theplurality of channels (B1˜B9) may include the selected channel (A) ifdesired, but in another example, the plurality of channels tuned to bythe second tuner may be different from the channel tuned by the firsttuner.

The second tuner 112 receives an image through a first channel (B1)among the plurality of channels (B1˜B9) for a first preset time (d1),and the received images from the first channel (B1) are stored in thememory 140. Once the first preset time (d1) lapses, then the secondtuner 112 receives an image through a second channel (B2) for a secondpreset time (d2), and the received images from the second channel (B2)are stored in the memory 140.

In the same manner, the second tuner 112 receives images through each ofthe other channels (B3˜B9) for each of the preset times (d3˜d9)respectively and the received images from these channels are stored inthe memory 140. Once the second tuner 112 receives an image through theninth channel (B9) for the ninth preset time (d9), the second tuner 112may again receive an image through the first channel (B1) for the presettime (d1). The second tuner 112 may sequentially receive images throughthe first to ninth channels (B1˜B9), which may be repeatedly performed.

Accordingly, the stored images from each channel for each preset timewould be displayed respectively on different regions of the screen,simultaneously.

The first to ninth preset times (d1˜d9) may be set to have the sameduration, or may be differently set according to a set status by a useror the controller 130, or a broadcasting reception status, etc.

The images sequentially received by the second tuner 112 through each ofthe plurality of channels (B1˜B9) are stored in the memory 140. Theimages sequentially received by the second tuner 112 through theplurality of channels (B1˜B9) may be stored in the memory 140 in anupdated manner. The images stored in the memory 140 may be deleted as apreset time lapses. Here, the images stored in the memory 140 may bedeleted in a firstly stored order in the memory 140, or according to auser's preset order.

The second tuner 112 may tune to a single channel at a time such that itcan tune to each of the multiple channels sequentially. In a variation,the second tuner 112 may be able to tune to multiple channelssimultaneously.

FIGS. 4A to 4D are different examples of a screen of an image displayapparatus in a channel information function mode according to anembodiment of the present invention.

In a normal operation mode, a user may be viewing images from a singlechannel (e.g., channel (A) tuned to by the first tuner) on the entirescreen of an image display apparatus. Then the user may select a channelinformation function mode, e.g., using the user input unit 160. In thechannel information function mode, images tuned to by the second tunerand stored in the memory 140 are displayed on one or more regions of thescreen.

For instance, as shown in FIG. 4A, images sequentially received throughthe plurality of channels (B1˜B9) and stored in the memory 140 may bedisplayed on a screen of the display unit 123 together with an imagereceived through the selected channel (A). In this example, the screenis divided visually (but not necessarily physically) such that theprogram of the channel A is displayed on one region of the screen whilethe programs (stored images) of the other channels (B1-B9) are displayedon the other regions of the screen. As a result, the user can view all10 channels (A and B1-B9) simultaneously. Here, it should be clearlyunderstood that all images (including the stored images) displayed onthe screen are moving images although the images may include staticdata/pictures. If the channels A and B1-B9 are showing different movies,then the screen would be showing these 10 movies simultaneously throughthe different regions of the screen. In this regard, while the programof the channel A may be continuously displayed on one region of thescreen since the first tuner continuously tunes to the channel A, theprograms from the other channels B1-B9 may be displayed with certainportions thereof being skipped since the second tuner only sequentiallytunes through the channels B1-B9 as shown in FIG. 3. The user canregardless view the programs (parts thereof) of these channels B1-B9 anddecide to select one of these channels for main viewing (e.g., to bedisplayed on the entire screen) if desired.

As shown in FIG. 4A, a cursor (C) may be displayed on at least oneregion (showing the channel B5) of the screen. The position of thecursor (C) may be varied by a user's manipulation through the user inputunit 160. The user input unit 160 may be provided at the image displayapparatus, or may be implemented as a remote controller. For instance, auser may select a menu item or button (or perform some other act) todisplay a cursor, and may move the cursor to a region of the screen thatis displaying a desired channel. The user may select a menu item orbutton (or perform some other act) to activate the cursor on the desiredregion, which in turn may cause the corresponding channel to bedisplayed for main viewing or may cause some other operation.

In order to vary the position of the cursor (C) through the user inputunit 160, the user input unit 160 may be provided with buttons indicatedby arrows or jog dials.

For instance, as shown in FIG. 4A, under a state that the cursor (C) isdisposed on a region of the screen for displaying an image of onechannel (channel B5) among the plurality of channels (B1˜B9), when auser presses a button, e.g., up arrow (↑), the cursor (C) may be movedupwardly and then displayed on a region of the screen for displaying animage of another channel B2.

In another example as shown in FIG. 4B, under a state that a channelinformation function (or other designated function) is selected, onlyimages sequentially received through the plurality of channels (B1˜B9)and stored in the memory 140 may be reproduced and displayed on thescreen. That is, the images from the channels B1-B9 that are displayedon the screen are stored moving images.

As shown in FIGS. 4A and 4B, the images sequentially received throughthe plurality of channels (B1˜B9) and stored in the memory 140 may bearranged in a two-dimensional manner. The regions of screen fordisplaying the stored images may be implemented so that these regionsfor displaying images received through predetermined similar channelsare arranged to be adjacent to one another. The predetermined similarchannels can indicate a set of channels classified as similar channelsby a broadcasting provider or a user.

For instance, when a user classifies cinema channels as main channels,the cinema channels are arranged to be adjacent to one another when achannel information function is executed. The classification may beperformed by a broadcasting provider or the controller 130.

As shown in FIGS. 4C and 4D, the images sequentially received throughthe plurality of channels (B1˜B9) and stored in the memory 140 may bearranged in a three-dimensional manner on the screen of the apparatus100.

As shown in FIG. 4C, the images sequentially received through theplurality of channels (B1˜B9) and stored in the memory 140 may bearranged on a surface of a sphere. When the images sequentially receivedthrough the plurality of channels (B1˜B9) and stored in the memory 140are reproduced on the screen in a three-dimensional shape (e.g.,sphere), manipulation icons D1 and D2 for manipulating thethree-dimensional shape may be additionally displayed on the screen.

As shown in FIG. 4C, once the user manipulates the first manipulationicon D1, the sphere currently displaying the channel B1-B9 on the screenmay be rotated in a first axis direction and then displayed. In thatcase, other channels (e.g., channels C1-C9) which may be assigned to theother side of the sphere, may then be displayed on the screen due to therotation of the sphere. As a result, not only the images sequentiallyreceived through the plurality of channels (B1˜B9) may be displayed onthe screen, but also other images from other channels may be displayedon the screen. Accordingly, a large number of different channels may beeasily manipulated on the screen and viewed by the user. Further, thesechannels can be grouped depending on similarity or other commonfeatures, and can be displayed in groups. For instance, in the aboveexample, the channels B1-B9 may be movie channels grouped by a user, andthe channels C1-C9 may be news channels grouped by the user. By a singleact of manipulating the icon D1, the user may view all of the user'sfavorite movie channels (displayed on one side of the sphere) and thenall of the user's favorite new channels (displayed on the other side ofthe sphere).

Once a user manipulates the second manipulation icon D2, the spheredisplayed on the screen may be rotated in a second axis direction andthen displayed. The first axis and the second axis may be disposed to beperpendicular to each other. Varying degrees of rotation by the firstand second manipulation icons D1 and D2 are possible.

In another example, as shown in FIG. 4D, the images sequentiallyreceived through the plurality of channels (B1˜B9) and stored in thememory 140 may be arranged on a surface of a polygonal shape, e.g.,hexahedron.

Once a user manipulates the user input unit 160, different surfaces Eand F of the hexahedron may be displayed on the screen. For instance,once the user selects the surface of ‘E’, a plurality of channels may bedisplayed on the surface of ‘E’ in a two-dimensional manner. The screenfor displaying a plurality of channels on the surface of ‘E’ in atwo-dimensional manner may be implemented as the same screen as that ofFIG. 4B. Similar to the examples of FIG. 4C, the different sides of thehexahedron may represent different groups of channels. Further,manipulation icons for manipulating and rotating the hexahedron may beprovided on the screen of the apparatus 100. In the examples where thechannels are represented in a three-dimensional manner, a cursor C mayalso be provided for selecting a particular channel for main viewing orfor other operation.

As shown in FIG. 4A, the controller 130 may activate a channelcorresponding to a region of the screen having the cursor (C) locatedthereon. Under a state that the image display apparatus 100 includes twotuners 111 and 112 as shown in FIG. 1, when a channel informationfunction is executed, images received through a selected channel (A) maybe displayed as shown in FIG. 4A. Here, the images received through theselected channel (A) may not be displayed in a case of FIG. 4B.

It is assumed that an image received through the selected channel (A) isdisplayed when a channel information function is executed as shown inFIG. 4A. In order for the controller 130 to activate a channelcorresponding to a region of the screen having the cursor (C) locatedthereon, one or more of the two tuners 111 and 112 have to receiveimages through the channel corresponding to the screen region having thecursor (C) located thereon.

In this case, the first tuner 111 that has been received an imagethrough the selected channel (A) may switch to and receive an imagethrough a channel corresponding to the screen region having the cursor(C) located thereon. In the example of FIG. 4A, if the cursor on thechannel B5 is activated, then the screen region showing the channel Amay then switch to the channel B5 and show the channel B5 continuously.On the other hand, the second tuner 112 may sequentially receive imagesthrough a plurality of channels (B1˜B9) and the selected channel (A).The images through the selected channel (A) and the plurality ofchannels (B1˜B9) are sequentially received by the second tuner 112, andare stored in the memory 140. That is, the second tuner 112 may now tuneto multiple channels including the channel (A) that was previously tunedto by the first tuner, so that this channel (A) is not lost and would bedisplayed on some region of the screen. In that case, one of the otherchannels B1-B9 may be removed, e.g., the second tuner may tune to thechannels A and B1-B8 such that the channel A and B1-B8 are thendisplayed simultaneously on the regions that previously displayed thechannels B1-B9 in FIG. 4A. Alternatively, the screen may be divided toinclude an additional region such that the channels A and B1-B9 may bedisplayed simultaneously on the regions that previously displayed thechannels B1-B9 in FIG. 4A.

The output unit 120 may display continuously an image continuouslyreceived through the selected channel (A) and stored in the memory 140.

Referring to FIG. 4B in this example, it is assumed that an imagereceived (e.g., by the first tuner) through the selected channel (A) isnot displayed in the activation of a channel information function. Inorder for the controller 130 to activate a channel corresponding to aregion of the screen having the cursor (C) located thereon, one or moreof the two tuners 111 and 112 may have to receive images through thechannel corresponding to the region of the screen having the cursor (C)located thereon. For instance, the first tuner 111 that has beenreceiving an image through the selected channel (A) may now switch andreceive an image through a channel corresponding to the region of thescreen having the cursor (C) located thereon. This may occur in responseto a user's input. At the same time, in an example, an image receivedthrough the selected channel (A) may not be displayed at all on thescreen of the output unit 120 as shown in FIG. 4B. Accordingly, theselected channel (A) may not be added to the plurality of channels(B1˜B9) through which the second tuner 112 sequentially receives images.The programs on the channels B1-B9 may now be displayed simultaneouslyon the entire screen. In an example, at this time, if a user selects aparticular one (e.g., B5) of the channels B1-B9 using a cursor C asshown, then the entire screen may display only the program of theselected channel B5.

In FIGS. 4A and 4B (and other applicable figures), some (e.g., B6-B9) ofthe regions of a screen are shown as blank while other regions (e.g., A,B1-B5) of the screen are shown with pictures of people, animals, etc.Although some regions may be shown as blank (which is shown as such forthe sake of brevity), preferably each and all of the regions of thescreen are simultaneously displaying programs or other signals that werereceived through respective channels (e.g., broadcast channels,communication channels, etc.) corresponding to the regions of thescreen.

In another example of FIG. 5, regions in a screen for displaying theimages sequentially received through the plurality of channels (B1˜B9)and stored in the memory 140 may be formed to have a polygonal shape.Here, the polygonal shape may be a hexahedron as an example only, butcan be any other shape.

It is assumed that the cursor (C) located on one region of the screencan be moved onto an adjacent region of the screen whenever the userinput unit 160 is manipulated by a user. Here, the number of channelsthat can be selected through a single manipulation of the user inputunit 160 may correspond to the number of edges of a region of the screenfor displaying an image.

For instance, as shown in FIG. 5, it is assumed that each region of thescreen is formed in a hexahedron shape. For example, when the userdesires to move the cursor (C) currently located on the region fordisplaying channel B6 ha, the user has only to move the cursor (C) tothe adjacent region (B2, B3, B5, B7, B9 or B10) through a singlemanipulation. Accordingly, the number of the regions of the screen ontowhich the cursor (C) can move by a user's single manipulation, in thisexample, is six. For this operation, the user input unit 160 may includean appropriate mechanism or device (e.g., designed menu buttons, joystick, etc.) so that the cursor may be moved in one of six differentdirections.

As shown in FIG. 5, when the regions of the screen for simultaneouslydisplaying images sequentially received through the plurality ofchannels are formed in hexahedron shapes, the number of channels thatcan be selected through one or two manipulations may be 18. As shown inFIG. 4A or 4B, when the regions of the screen for simultaneouslydisplaying images sequentially received through the plurality ofchannels is formed in a rectangular shape, the number of channels thatcan be selected through one or two manipulations may be 13. From theabove explanations, it can be inferred that the more the number of edgesof the regions of the screen for displaying the plurality of channelsis, the more channels can be selected through a user's manipulations.

FIGS. 6A to 6D are examples of views showing that a size of a region ofa screen having a cursor located thereon can gradually increase ordecrease with respect to the entire screen size according to lapses oftime according to an embodiment of the present invention.

As shown in FIG. 6A, once the cursor (C) is located on a region of ascreen of an image display apparatus (e.g., apparatus 100) fordisplaying an image received through one channel (e.g., B5) among aplurality of regions of the screen for displaying simultaneously imagesreceived through the plurality of channels, the controller 130 mayactivate the region (i.e., channel B5) identified by the cursor (C).Here, the cursor may be placed on the region and the mere placement ofthe cursor may activate that region. In a variation, once the cursor isplaced on the region, an additional act (e.g., additional input oractivation) may be needed to activate the region. Further, in this andother examples, the cursor (C) can be represented in any manner, shapeor configuration. For example, a sign or symbol representing the cursormay be placed on a corner area of a region of the screen.

As shown in FIG. 6B, once the region (e.g., for displaying the channelB5) identified by the cursor C is activated, the size of that region maygradually increase with respect to the entire screen size according tolapses of time, or instantly increase to a large size.

Referring to FIG. 6B, in this example, the region of the screen havingthe cursor (C) located thereon has a size that gradually increased withrespect to the entire screen size while maintaining its shape (e.g.,rectangular shape). However, the region of the screen having the cursor(C) located thereon may have a size gradually increased with respect tothe entire screen size in variable shapes, e.g., as the size increases,the shape of the region may also change.

As discussed above, the size of the region of the screen having thecursor (C) located thereon may immediately increase, or may increase asa certain time lapses after the cursor (C) is displayed thereon.

As shown in FIG. 6C, the size of the region of the screen having thecursor (C) located thereon may gradually increase with respect to theentire screen size, such that that region is fully displayed on theentire screen of the image display apparatus.

As shown in FIG. 6D, the region of the screen having the cursor (C)located thereon may be set as a main channel (A) as a certain timelapses. This may occur automatically in the image display apparatus, ormay be manually set by the user. Once the region (e.g., for displayingthe channel B5) having the cursor (C) located thereon is set as a mainchannel, the controller 130 may treat the channel B5 as the main channeland may end the channel information function. Here, the first tuner maynow tune to the channel B5 as the main channel, and the cursor maydisappear.

FIGS. 7A and 7B are another example of conceptual views for showing thata ratio of time taken for a second tuner to receive an image through achannel corresponding to a region of a screen having a cursor locatedthereon, with respect to time taken to receive images through all otherchannels is increased according to an embodiment of the presentinvention.

When images received through a plurality of channels and stored in thememory 140 are to be simultaneously displayed on the screen underactivation of a channel information function, it is assumed in thisexample that the cursor (C) is located on a region of the screen fordisplaying an image received through one channel (e.g., channel B1)among a plurality of channels.

The controller 130 may vary or increase the duration of time forreceiving an image through the channel B1 corresponding to the region ofthe screen having the cursor (C) located thereon, with respect to theduration of time for receiving images through other channels, when thesecond tuner 112 sequentially receives images through the plurality ofchannels (e.g., channels B1˜B9).

More specifically, as shown in FIG. 7A, when the cursor (C) is notdisplayed or placed on the screen, it is assumed that each time (d1˜d9)for which the second tuner 112 receives images through each channel(B1˜B9) is set to have the same duration. For instance, when the cursoris not used or involved, the second tuner 112 tunes to the channel B1for a time duration of d1, and then tune to the next channel B2 for atime duration of d2, and then tune to the next channel B3 for a timeduration of d3, and then tune to the next channel B4 for a time durationof d4, and so on, where all the time durations d1, d2, d3, d4, . . . arethe same or substantially the same.

On the other hand, as shown in FIG. 7B, when the cursor is used orinvolved, the controller 130 may increase the time duration (d1) forwhich an image is received through the channel B1 corresponding to theregion of the screen having the cursor (C) located thereon, whiledecreasing the other times (d2˜d9). For instance, if the cursor islocated on or used to activate a particular region (e.g., for displayingchannel B1), then the second tuner 112 may tune to the channel B1 for atime duration of d1, and then sequentially tune to the other channelsfor time durations of d2-d9, where d1 is larger than any one of d2-d9and where d2-d9 are equal to each other.

As a variation, the user may be able to variably and independently seteach of the tuning time durations (e.g., d1, d2, d3, . . . ) for each ofthe first and second tuners 111, 112 as desired.

FIG. 8 is a block of an image display apparatus according to anotherembodiment of the present invention.

As shown in FIG. 8 in this example, the image display apparatus 100 ofFIG. 1 may be implemented so that the broadcasting reception module 110can further include a third tuner 113. All components of the imagedisplay apparatus 100 of FIG. 8 are operatively coupled and configured.

The third tuner 113 may receive an image through a channel correspondingto a region of a screen having the cursor (C) located thereon. That is,a separate tuner may be provided to tune to a channel identified by thecursor on the screen of the display unit 123.

In this embodiment, in the example of FIG. 4B where the channel B5corresponding to the region of the screen having the cursor (C) locatedthereon is to be activated under a state that the previously selectedchannel A is not displayed on the screen, the first tuner 111 mayreceive an image through the channel B5. Then the controller 130 maycontrol the display unit 123 so as to display an image received by thefirst tuner 111 (i.e., channel B5) on the screen having the cursor (C)located thereon. As a result, the channel B5 may be displayedcontinuously (e.g., in real time) as it is tuned to by the first tuner111. On the other hand, the other regions of the screen rather than theregion for displaying the channel B5 having the cursor (C) locatedthereon may display stored images retrieved from the memory 140, whichare still moving images (and not just still pictures).

In the example of FIG. 4A when the channel B5 corresponding to theregion of the screen having the cursor (C) located thereon is to beactivated under a state that an image received through the selectedchannel A is displayed on the screen, the controller 130 may control thefirst tuner 111 so as not to receive an image of the channel (B5), inorder for the first tuner 111 to continuously receive an image throughthe selected channel (A) and for the display unit 123 to display thereceived image of the channel A on the screen while the other channelsincluding the channel B5 are displayed at the same time.

FIG. 9 is an example of a conceptual view showing a status that an imageis being received through a channel corresponding to a region of ascreen having a cursor located thereon according to an embodiment of theinvention. For example, the third tuner may tune to a channel having acursor located thereon so that the images of that channel maycontinuously be displayed directly from the third tuner.

In the example of FIG. 4A, the controller 130 may control such that thethird tuner 113 receives an image through the channel B5 correspondingto the region of the screen having the cursor (C) located thereon, andthe image received by the third tuner 113 is displayed on the region ofthe screen having the cursor (C) located thereon. For instance, theimages of the channel B5 on the screen may not be the stored images fromthe memory 140, and may be images fed directly from the third tuner 113.As a result, the images of the channel B5 may be displayed continuouslywithout interruptions or skipped areas. In this example, the first andsecond tuners 111 and 112 may operate as discussed above.

According to an embodiment, the user can select which channels may besimultaneously displayed on the screen of the image display apparatus,and/or how many channels may be simultaneously shown on the screen.Further, the channel guide information for each channel may besimultaneously displayed on each region of the screen while the programsof those channels are being displayed. As a variation, if specificchannels exist solely for providing channel guide information or othertype of information associated with programs, then those channels can beincluded in the plurality of channels to be tuned to by any one of thetuners of the broadcasting reception module of the image displayapparatus 100. As a result, such information may also be simultaneouslydisplayed on certain regions of the screen.

The present invention is applicable to any display device, and isadvantageous for various reasons discussed above. For instance, multiplesignals, images, etc. from a large number of different channels can besimultaneously displayed don the display device with use of just twotuners or three tuners. Further, depending on the set up configurations,the manner and time duration of displaying each of these channels may bemanaged in an effective and user-friendly manner.

For instance,any example, feature, and variation discussed above according to any oneof various embodiments may be combined or applied in any otherembodiment discussed above.
